This invention relates to devices for manipv ulating the depth control rand'similar levers of plows, cultivatorsjharrows, and any other implements arranged to be drawn by a trac- 5 tor or similar draft means, and provided with levers which require manipulation lat onel time or another while operations are being carried on. Y l

The principal object of my invention is to provide a device, adapted to be detachably applied to a tractor j and to the levers ofl thel implement, and so arranged that the driver of the tractorl can manipulate all the levers Y of the implements` simultaneously without stopping the movement of the implement and 25 itated.

A further obj ect of the invention is to produce a simple andA inexpensive device and yet one which will be exceedingly effective for the purpose for vwhich it is designed.

These objects Iaccomplish'by means of such structure and relative arrangement lof parts as will fullyappear by a perusal of the fol- Y lowing specication and claims. Y. f

F ig. 1 is a perspective elevation of my lever controlatta'chment as in operation and shown in connection with a S-unit vgang harrow.,y

Fig. 2 is a fragmentary cross section of the attachment. l x

Referring `to the numerals of reference on the drawings, l denotes the usual drawhead of the tractor which as shown here is connected by suitable and customary means gto three transversely alined harrow frames 2, the vertical position of whose teeth supporting bars 3 is controlled by separate upstanding levers 4.' These levers are'u'sual-ly associated with pawl and ratchet holding mechanisms, which I haver not shown since in applying myvat-r vrtachm'ent I remove such mechanisms orrenv der the sameinef'tective. u

' Myeimproved .leveroperating attachment, to control all the levers simultaneously from 5 the tractor,A comprises Va longitudinahbar 5 pivotally connected to the drawhead'v 1 and extending rearwardly therefrom. Pivoted on thisv bar intermediate its ends is an upstandring lever 6 having pawl and ratchet holding 6U mechanism indicated generally at 7 associated therewith. Pivotally connected to this lever ares'ubstantially horizontal links 8 which at .their-forward ends straddle the lever and which diverge thence rearwardly to extend to '65 the outermost levers l, to which levers said#v links are pivotally connected as at 9. The central leverft is connected to a straight link l0 which extends forwardly to a pivotal con-f* nection with thevlinks`8rjust rearwardly of 70 the lever 6. It'will therefore be seen that if the lever 6 is turned one way or the other, all v the'vlevers l will besimultaneously moved' l 4so that all said levers are controlled from the single lever 6. All vthe links are provided v75 with longitudinally extending series of holes ll near their ends, so that they may befconnected at different points in their lengthto` the corresponding levers as may be required for adjustment purposes with different- 'iinple-V 80 ments. i j ,Y Projecting transversely under the links 8 ahead of thel rear end ofthe bar 5 4isa cross bar to which said links areclamped byv U bolts l13 or the like. Strapsll project down- 85 wardly from the cross -bar in converging rela-`- tion to the bar' 5 and then extend downwardly along side saidbaras shown. vvBoltsyl i* through said straps aboveand below the' bar 5 connect the straps together and form a guide 90 and supporting 'structure for the barY 5 through which the'latter is relatively slidable. Diagonally and 'rearwardly extending brace straps 16 extend from thelower `endsof the' straps 14 to connections Vwith the -links 8 at 95 4 p adjustable points in the length of the latter.

AIt will thereforexbe seen that the bar 5 is supported against sagging by the'bar '12 and the guide structure depending fthere- Vf from, without interfering with t-he longitudi'` 100 'Y i nal movement of the links hadwhen the lever 6 is swung one way or the other. The bolts 15 are spaced a sufficient distance apart so that said bar can have the necessary vertical play as the links, and consequently thev bar support and guide, move up or down relative tosaid. bar with. the movement of the .lever ingeither; directionpast a vertical position. This arrangement also permits of the inevitable vertical play between the implelment' and the tractor being had' without interference, since, the variouslinks are pivoted.

both Ato the leverv 6` andto the implement levers 4. ffthe implement only-'has twoy levers, the central link l() is removed. and the links 8; aredrawn in closer to. engagethe two remaninglevers; .In thiszcase the U bolts A1:3 are removed from their: original positions; as shawn. and are. `replaced further in alongv the` banll, the.4 latter. having correspondingly: disposed holesa as shownatlf; forthe reception l .Y cfs said bolts. Likewise the brac-e straps 16.
